Solenodon paradoxus

Solenodon paradoxus can be found exclusively on the island of Hispaniola in Haiti and the Dominican Republic. Most specimens have been discovered in northern Hispaniola. Solenodon paradoxus can be found in wooded and brushy areas, often near areas of agriculturally developed land. Because solenodons are nocturnal they find shelter during the day in tunnel systems that they construct by burrowing through organic material and soil. They also take refuge in hollowed logs and trees, caves, and cracks in rocks.

Solenodon paradoxus looks much like a shrew. However, it is considerably larger. A black to reddish-brown pelage covers the majority of the body, with the exception of the tail, feet, nose, and tips of the ears. The forelimbs are considerably more developed than the hindlegs, but all limbs have claws presumably for digging.

Its heads is large in proportion to its body and the rostrum is elongated. A defining characteristic of Solenodon paradoxus is the os proboscis, a bone (which supports a long cartilaginous snout) located on the tip of the rostrum. This species' dental formula is 3/3, 1/1, 3/3, 3/3 = 40. The second lower incisor has a groove from which venom is secreted from a mandibular gland. Males of this species have an unexposed penis and testes residing deep within the abdominal cavity.

Little is known about the mating system and behavior of Solenodon paradoxus. Before mating, the female constructs a nest in which she will birth and nurse her young. It is known that females have an estrus period that irregular and not coordinated with the seasons. Males, in contrast can mate at any time. When first introduced to each other, solendons may engage in aggressive behavior, but it is unknown whether this is an attempt at sexual dominance.

Different types of science communications such as systematic or brief reviews, original research articles, letter-to-editor, commentaries, theoretical perspectives, survey observations are accepted by the journal. The journal also articulates theoretical perspectives and expert opinions on the current and emerging approaches, practices and management in poultry, fisheries and wildlife.
